Inefficiency bugs me... You can do multiple patterns with a single grep using
the -e flag.
grep -v -e ^# -e ^$ clamd.conf
Try (and there are surely others even shorter)
egrep -v '^(#|$)' clamd.*f
That works too, but I was more concerned with the extra grep process
than anything else. You also lose a bit of readability that way as you
have to parse the (admittedly simple) regexp to figure out what it is doing.
